Uhlobo lwe-MD lwempompo ye-centrifugal oluxhathisa ukunxitywa kwe-multistage

Ingcaciso yeMveliso
Impompo ye-centrifugal yodidi lwe-MD ekwazi ukumelana nenqanaba elinye yimpompo ye-centrifugal enenqanaba elinye elithe tye, elamkela imodeli yobuchwephesha bokusebenza okuphezulu kunye nemveliso yokonga amandla ecetyiswa ngurhulumente, kwaye ikwindawo ephambili kubuchwephesha kwitekhnoloji. ishishini.Inenzuzo yokusebenza okuphezulu, uluhlu olubanzi lokusebenza, ukusebenza okukhuselekileyo kunye nokuzinza, ingxolo ephantsi, ubomi obude, ukufakwa kunye nokugcinwa ngokufanelekileyo, njl. Olu hlobo lwempompo ye-centrifugal ye-multi-stage centrifugal yemigodi isetyenziselwa ukuthutha amanzi amaminerali angathathi hlangothi (ubungakanani besuntswana). ngaphantsi kwe-0.5 mm) kunye nesiqulatho esiqinileyo se-particle engekho ngaphezu kwe-1.5% kunye nolunye ugutyulo olufanayo.Izityalo zentsimbi, imisele yamanzi, ukuthuthwa kwamanzi amdaka kunye nezinye izihlandlo.

Iiparamitha zokusebenza
Imodeli yentsingiselo kunye neemeko ezisebenzayo zempompo ye-MD enganyangekiyo yamanqanaba amaninzi emigodini:

1. Ngaphantsi kweemeko zamanzi acocekileyo (kunye neengqungquthela eziqinileyo ezingaphantsi kwe-0.1%), ukusebenza kakuhle akuyi kuhla ngaphezu kwe-6% emva kokuqhuba i-5000h ngaphandle kokulungiswa;
2. Ngaphantsi kweemeko zamanzi amdaka aqukethe amaqhekeza aqinileyo phantsi kwe-0.1% ukuya kwi-1%, eqhuba i-3000h ngaphandle kokulungiswa, ukuhla okusebenzayo akudluli i-5%;
3. Ngaphantsi kweemeko zamanzi amdaka aqukethe iinqununu eziqinileyo ze-1-.5%, ukusebenza kakuhle akuyi kuhla ngaphezu kwe-6% ukuba iqhubela i-2000h ngaphandle kokulungiswa okukhulu.
Iimpawu zesakhiwo sohlobo lwe-MD oluxhathisa ukunxitywa kwempompo ye-centrifugal yamanqanaba amaninzi emigodini:

Inxalenye yestator iqulunqwe ikakhulu licandelo langaphambili, icandelo eliphakathi, i-vane yesikhokelo, icandelo elingasemva, isakhelo sokuthwala kunye nesigqubuthelo segumbi lokulinganisa.Amalungu adityaniswe nentonga kunye ne nut.Icandelo langaphambili kunye necandelo elingasemva ligxininiswe kwisitulo sempompo kunye neebholiti kunye namantongomane.
Amacandelo e-rotor ayenziwe ngokukodwa nge-impeller, i-impeller block, ibhloko yebhalansi, i-balance disc kunye neengxenye zemikhono ye-shaft ziqiniswe ngamantongomane amancinci ajikelezayo, kwaye zigxininiswe kwi-shaft kunye nezitshixo ezinqamlekileyo zokuthintela ukujikeleza.I-rotor yonke ixhaswa kwiibheringi kuzo zombini iziphelo.I-rotor ixhunywe ngokuthe ngqo kwi-motor kunye ne-pin elastic coupling.
Ukuze uhlawulele ukwandiswa, i-pad yamazinyo ifakwe phakathi kwesigaba sokugqibela kunye nomkhono webhalansi, omele utshintshwe xa umpompo ugqitywe.
Ipompo ye-centrifugal enezigaba ezininzi zokumbiwa kwemigodi yokunxiba ithatha i-balance plate hydraulic balance device enokuthi ilungelelanise ngokupheleleyo kwaye ngokuzenzekelayo i-axial force.Isixhobo sineenxalenye ezine: i-balance plate, i-balance plate, i-balance plate kunye ne-balance block.
Inxalenye ye-rotor yohlobo lwe-MD ye-mining impompo ye-centrifugal ye-multistage iqulunqwe kakhulu yi-shaft kunye ne-impeller, i-shaft sleeve, i-balance disc kunye nezinye iindawo ezifakwe kwi-shaft.Inani le-impellers lixhomekeke kwinani lezigaba zempompo.Amacandelo e-shaft agxininiswe ngesitshixo se-flat kunye ne-nut nut ukuba ihlanganiswe ne-shaft.I-rotor yonke ixhaswa ngokuqengqeleka kweebheringi okanye i-sliding bearings kuzo zombini iziphelo.Iibheringi zichongwa ngokweemodeli ezahlukeneyo, kwaye akukho namnye kubo othwala i-axial force.Amandla e-axial alungelelaniswa yi-balance disc.Ngethuba lokusebenza kwempompo, i-rotor ivumelekile ukuba ibhukude i-axially kwi-casing yepompo, kwaye iibhola zebhola ze-radial azikwazi ukusetyenziswa.I-rolling bearing i-lubricated ngeoli, i-sliding bear lubricated nge-oyile encinci, kwaye i-oil ring isetyenziselwa i-self-lubrication, kwaye amanzi ajikelezayo asetyenziselwa ukupholisa.Imiphezulu yokutywina phakathi kwecandelo lokungena kwamanzi, icandelo eliphakathi kunye necandelo lokuphuma kwamanzi lempompo zonke zitywinwe ngegrisi ye-molybdenum disulfide, kunye nomsesane wokutywina kunye nomkhono we-vane wesikhokelo ufakwe phakathi kwenxalenye yerotor kunye nenxalenye emiselweyo yokutywinwa.Xa iqondo lokugqoka kunye nokukrazula lichaphazele ukusebenza kompompo, kufuneka litshintshwe.
Iindlela zokutywinwa kweempompo ze-multistage centrifugal zibandakanya ukutywinwa koomatshini kunye nokupakisha amatywina.Xa ipompo ivalwe ngokupakisha, indawo yendandatho yokupakisha kufuneka ichaneke, ukuqina kokupakisha kufuneka kube ngokufanelekileyo, kwaye kuyacetyiswa ukuba i-liquid ikwazi ukubona i-drop by drop.Izinto ezahlukahlukeneyo zokutywinwa kompompo zifakwe kwindawo yokutywina, kwaye i-cavity kufuneka izaliswe ngamanzi oxinzelelo oluthile, kunye nokutywinwa kwamanzi, ukupholisa kwamanzi okanye ukuthambisa amanzi kunokuzikhethela.I-bushing enokutshintshwa ifakwe kwi-shaft seal ukukhusela i-shaft yepompo.
Isalathiso sokujikeleza kolu hlobo lwempompo ye-centrifugal enezigaba ezininzi ijika ngasekunene xa ijongwe kwicala lemoto yokuqala.
Imiyalelo yokuqalisa impompo:

Ngaphambi kokuqala i-mini-stage centrifugal pump, i-rotor yepompo kufuneka ijikelezwe ukujonga ukuba i-rotor iguquguqukayo;
Khangela ukuba ingaba isalathiso semoto siyahambelana na necala lempompo;
Vula ivalve yempompo yokufunxa, vala ivalve yesango lombhobho ophumayo wempompo kunye neqhude legeyiji yoxinzelelo, ukuze impompo izaliswe lulwelo, okanye usebenzise inkqubo yokufunxa ukususa umoya kumbhobho wokufunxa kunye nempompo;
Khangela ukunyanzeliswa kweebholiti zokudibanisa ipompo kunye nemoto kunye nokhuseleko olujikeleze umpompo, ukwenzela ukuba umpompo ulungele ukuqala;
Qala injini.Emva kokuba impompo ibaleka ngokuqhelekileyo, vula igeji yokulinganisa uxinzelelo kwaye uvule ngokucothayo ivalve yesango lokuphuma kwempompo de isalathisi soxinzelelo sikhombe kuxinzelelo olufunekayo (lawula ukunyuswa kwempompo ngokwegeyiji yoxinzelelo lokuphuma).

Ukusebenza
Umpompo we-centrifugal ongaguqukiyo wamanqanaba amaninzi kwimigodi usebenzisa indlela yokulinganisa kwimpompo ukulinganisa amandla e-axial.Ulwelo olulinganayo luphuma kwisixhobo sokulinganisa.I-balance balance liquid idibene necandelo lokungena kwamanzi ukusuka kumbhobho wamanzi wokulinganisela, okanye umbhobho omfutshane wenzelwe kwigumbi lokulinganisa.Umbhobho uphuma kumpompo.Ukuze kuqinisekiswe ukusebenza okuqhelekileyo kwempompo, umbhobho wamanzi wokulinganisela akufanele uvalwe;
Kwinkqubo yokuqala kunye nokusebenza, kufuneka ubeke ingqalelo ukujonga ukufundwa kweemitha, nokuba ukufudumeza ukuthwala, ukupakisha ukuvuza kunye nokufudumeza, kunye ne-vibration kunye nesandi sempompo ziqhelekileyo.Ukuba kufunyenwe nayiphi na imeko engaqhelekanga, kufuneka kujongwane nayo kwangethuba;
Ukutshintsha kweqondo lokushisa elithweleyo libonisa umgangatho wendibano yempompo, ukunyuka kweqondo lokushisa akuyi kuba ngaphezulu kwe-35 ℃, kwaye iqondo lokushisa eliphezulu aliyi kuba ngaphezulu kwe-75 ℃;
Kukho intshukumo ethile ye-axial ye-rotor yepompo ngexesha lokusebenza, kwaye ukunyakaza kwe-axial kufuneka kube ngaphakathi kwinqanaba elivumelekileyo, kwaye ixabiso lokucoca phakathi kobuso bokugqibela bemoto kunye nokudibanisa ezimbini kompompo wamanzi kufuneka kuqinisekiswe;
Ngexesha lokusebenza kwempompo, ukunxiba kwe-impeller, ikhonkco lokutywina, umkhono we-vane wesikhokelo, umkhono we-shaft, i-balance disc kunye nezinye iindawo kufuneka zihlolwe rhoqo.Ukuba ukunxiba kukhulu kakhulu, kufuneka kutshintshwe ngexesha.

Yeka
Phambi kokuvalwa, inkuku yegeyiji yoxinzelelo kufuneka ivalwe, kwaye ivalve yesango lokuphuma kufuneka ivalwe kancinci.Emva kokuba ivalve yokuphuma ivaliwe, i-motor kufuneka ivalwe.Emva kokuba umpompo uyeke ukuzinza, ivalve yokufunxa yempompo kufuneka ivalwe;amanzi kwimpompo kufuneka akhululwe.Icociwe kwaye ifakwe i-oyile, ipakishwe ukuze igcinwe.
